In a four-page letter to Sonia, dated July 1, the second from him in three weeks, Nath has charged Roy with taking unilateral decisions and hurting the party's image just before the panchayat polls. Nath alleges that because of Roy's ``ignorance'', the Congress failed to allot forms to candidates in over 700 seats leaving them uncontested in favour of the Left Front.

Nath also said his letters were being leaked to the media from 10, Janpath.
